ELMER FRANKLIN BUBB, OF CHICAGO, ILLINOIS.

AUTOMATIC SWITCH.

Specification of Letters Patent.

Patented Nov. 23, 1909.

Application filed July 29, 1909. Serial I10. 510,193.

To all whom 'it may concern:

cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Automatic Switches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled I illustrate my invention in the accompanying drawings, in which Figure l is a top plan view of my improved switch system. Fig. 2 is a vertical longitudinal section showing parts of the invention in elevation. Fig. 3 is an enlarged detail perspective View. Fig. 4 is a sectional view through the floor of a car showing means for actuating the switch mechanism, and Fig. 5 is an enlarged detail perspective view of a part ofthe invention.

Reference now being had to the details of the drawi gs by letter, A designates the rails of a railw y and B the ties upon which the rails are fastened. Mounted in the bearings C which are secured to the under sides of the ties is a rock shaft D havin angled ends D, shown clearly in'Fig. 3 of t e drawings, and E, E designate lates having each an angular openin con orming to the angled end of the rock s aft D.

F is a cotter pin or. ke passing through an aperture in the angle end of the shaft adapted to hold the plate E thereon. In the drawings I have shown a plate E-fastened in a similar manner-to each end of the shaft.

Keyed to the shaft D is an arm H having pivotally connected thereto a linkKwhich in turn is connected to the switch point I,

mounted to have a longitudinal movement in the vertical bearing members O'. The pins N are adapted to pass through and be guided in the slots E and, as the plate is rocked with the shaft, said rods 0 are moved longitudinally. Pivotally connected to the upper end of each rod 0 is a pin Q, assing through registering apertures Q, in t e ends of the two plates S and T, shown clearly in Figs. 2 and 5 of the drawings. In said views, it will be noted that the end of the plate S has a recess S therein adapted to receivethe two lugs T which are apertured, the fastening pin extending through registering apertures in the two plates and rod The outer ends of the plates T are left preferably free and are adapted to rest upon the ties in the manner shown in the drawings, It will be understood that one pair of plates S and T is adapted to throw the switch point toward the mainrail while the other pair adjacent thereto is designed to cause the plate E to tilt in an opposite direction for throwing the point away from' the main rail.

[pin fastened to a rod 0 which latter is Be it known that I, ELMER F. BUBB, a

citizen of the United States, residing at Chi- In order to throw the switch, any kind of mechanism carried bya moving car passing over the tracks may be employed, such as is' shown in Figs. 2 and 4 of the drawings, in which I have shown the two spring posts J having collars J thereon to bear against the under surface of the floor L of a car and coiled s rings L interposed between the u per surfhce of the platform and the head 2 and at the lower end of each post'is journaled a wheel P adapted to be moved so as to contact with the upper faces of the plates S and T as the car moves in one direction or the other, the contact between the rollers P and the plates S and T causing the latter to be depressed for the purpose of rocking the shaft D which, through its connection with the switch point, will operate the latter toward or away from the main line rail.

What I claim to be new is An automatically operated switch comprising, in combination with the ties and main rails bf a railway and the pivotal switch point, a horizontally disposed rock shaft mountedin suitable bearings underneath'the ties, connections between the rock shaft and-switch point, a plate fixed to said rock shaft and having slots therein, vertically disposed rods having sliding pivotal 1 In testimony whereof I hereunto affix my COIlIliCitlOglS with said slots and nliounted in signature in the presence of two witnesses. suita e ear-in s u on t e ties, epressing plates pivotally con ected to the u per ends ELMER FRANKLIN BUBB' 5 of said rods and normally inclined with Witnesses:

their free ends slightly curved and resting OSCAR HEssLER, upon the ties, as shown and described. ALBERT HEIN.
